What makes people with arthritis feel extensive pain during the cold?

Question:

Just wondering why they feel so much pain when they are cold.. plus people with injuries.

Answers:
There is "high" and "low" air pressure areas all over the earth. It's part of our weather.
The air pressure usually decreases (it gets "low") when it's cold outside (also when it rains or is about to rain).
Human joints have bursa, or small cushiony sacs around them. The bursa swell and press against nerves when the air pressure drops, which causes pain.
If there are bursa around any injury, the same pain will happen for the same reason.

people with arthritis also can feel pain before it rains.
